直导轨修理涉及许多方面,工艺方法多种多样,本文仅扼要阐明若干基本概念,希望有助于提高机修工和机修技术人员的分析能力与判断能力。一、基本精度要求导轨的功用。除保证溜板运动的方向精度外,还要承受切削力,单根导轨不能保证溜板稳定,通常都是相隔一定距离的两根导轨组合而成。在两根导轨的各个表面中,和溜板接触,直接起导向作用的表面为基准导轨面;和 Straight rail repair involves many aspects, a variety of process methods, this article only briefly illustrates some of the basic concepts, hoping to help improve the mechanic and mechanics of the analysis and judgment. First, the basic accuracy requirements of rail function. In addition to ensuring the accuracy of the direction of carriage movement, but also to bear the cutting force, a single rail can not guarantee the stability of the slide, usually separated by a certain distance between the two rails. In each of the two rails, the surface that comes into direct contact with the carriage and serves as the reference rail surface; and
